Sperm Travels Faster Toward Attractive Females

Its not shocking, but it is amazing that its SCIENCE.

A new study has shown that even sperm can be superficial. Researchers found that males of many animal species, including humans, can adjust the speed and effectiveness of their sperm by regulating the amount of seminal fluid they produce during copulation. The determining factor on that amount of fluid seems to be whether the male finds the female attractive.
